LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 705,898, dated July 29, 1902.

Application'filed November 18, 1901. Serial No. 82,617. (No model.)

To all whom, it may concern: assuming its normal position, in which it is 50 Beitknown that I,HENRYBARDsLEY,a citicapable of bringing about the special operazen of the United States, residing at Provition by means of which the prearranged redence, in the county of Providence, State of suit in the working of the loom is brought 5 Rhode Island, have invented a certain new about.

and useful Improvement in Loom-Shuttles, of The invention is capable of being variously 55 which the following is a specification, referembodied and applied in practice. It has once being had therein to the accompanying been designed more especially for utilization drawings. i r in connection with weft or filling wound in The invention relates to the devices which the form of cops instead of upon bobbins, al-

are employed in' loom-shuttles for the purthough it is not necessarily restricted in this 60 pose of ascertaining when the yarn -load particular. It will therefore be understood which is carried by the working shuttle of a that while I have represented in the accomloom has become exhausted or depleted to the panyin g drawings, and have herein described r predetermined extent and for calling into acwith reference to the said drawings, an emtion instrumentalities for bringing about a bodiment of the invention suitable for use in 65 prearranged change in the working of the connection with yarn in cop form the invenloom. p tion is not in all cases limited to application The invention consists in improved devices to shuttles employing weft or filling in such of the said class and will first be described form. In the said embodiment the weft-rewith reference to the drawings, in which latoeiver is constituted by the usual shuttle- 7o ter is represented an embodiment of the inspindle 2.

vention, after which the characteristic and Having reference to the drawings, 1 desigessential features thereof will be particuhates the shuttle-body; 2, the shuttle-spinlarlydefined in the claims at the close of this dle; 3, the pin upon which the head of the specification. said spindle 2 is mounted pi'votally, as indi- 75 In the drawings, Figure 1 shows in side ele cated in Fig. 2; arid 4, the usual. spindlevation a portion of a shuttle having the invenspring, the said spring being held in place by tion applied thereto. Fig 2 shows the same the screw 5 and bearing upon the head'of the mainly in central longitudinal section, the shuttle-spindle 2 in customary manner.

shuttle-spindle, however, being in elevation. The follower is shown at 6. It is located 80 Fig. 3 shows the same in plan, partly in horiupon the base portion of the spindle 2, closely zontal section. I adjacent the headfZ thereof, and is fitted to In carrying the invention into effect I emthe spindle blade with capacity to move ploy in aloom-shuttle, in connection with the lengthwise thereon. The said follower 6 is receiver on which is placed the working weftbacked up by a spring 7, which latter is com- 85 supply, a follower that is mounted to move in pressed between the said follower and the the direction of the length of the weft-respindle-head 2, the follower having an inceiver, the said follower being governed as to ternal chamber, as shown in Fig. 2, which resuch movement by the mass of yarn consticeives the said spring. A cop 8 of weft or filltuting the working weft-supply and a moving is shown in place upon the spindle 2 in 90 able trip or controller suitably mounted upon Fig. 3. In applying the said cop tothe spinor within the shuttle, held in abnormal or indle 2 the cop is pushed along the said spindle operative position by the said follower until until the base thereof has been forced against releasedby the movement of the follower the follower 6 and the latter has been moved lengthwise of the weft-receiver, which is pertoward the spindle-head 2*, so as to compress 5 mitted by the depletion of the working weftthe spring 7 and place the latter in a state of supply within the shuttle to the predeter-v increased tension. I mined extent, the said trip or controller then At 9 is represented a trip or controller,

which is pivoted to the shuttle-body 1 at 9 in the manner which adapts the same to swing horizontally, the said trip or controller 9 0ceupying a slot 9 which is formed in one side of the shuttle-body, at the end of the latter at which the shuttle-spindle is pivoted. The said trip or controller is backed up by a spring 11, the latter being located between one arm of the trip and the wood of the shuttle-body. The trip or controller may in practice be variously constructed, arranged, and combined in order to bring about the predetermined special action or operation in the working of aloom. invention it is formed or provided with an engaging end 9, which normally is caused to project outward beyond the side of the shuttie-body by the action of the spring 11. The outward movement of the said engaging portion'of the trip or controller 9 is limited by means of a stop-pin 12, with which the trip engages. It is intended that the engaging portion of the trip or controller 9 shall be allowed to project, as referred to, only after the.

supply or load of weft or filling which is conrained in the shuttle shall have become used up to the predetermined extent. To this end, so long as the quantity of yarn contained in the cop upon the spindle 2 is sufficient to keep the follower 6 in the position in which it is shown in Fig. 3, the said follower 6, by its ongagement with the tail of the trip or controller 9, will retain the said trip or controller in its retracted abnormal position, which is shown in Fig. 3. The trip or controller is retained in this position during the working of the shuttle until, as the weft or filling issues from the shuttle, the base portion of the cop becomes sufficiently unwound to permit the follower 6 to move lengthwise of the spindleblade, under the action of the spring 7, far enough to clear or escape from the tail of the trip or controller 9. As soon as the follower has thus cleared or escaped from the said tail of the trip or controller 9* the spring 11 acts to project the engaging portion 9 of the said trip or controller into position to engage in the flight of the shuttle with the instrumentalities which are provided for the purpose of bringing about the required change in the working of the loom in which the shuttle is being employed.

A shuttle having my invention applied thereto is equally well adapted to cooperate with instrumentalities for effecting automatically the replenishment of the working weftsupply in a loom and with instrumentalities for bringing about a stoppage of the loom without effectingreplenishment. Instrumentalities for both purposes are well known, and the manner of utilizing the invention in connection therewith will be obvious without further explanation to those who are skilled in the art.

It will be perceived that in the present embodiment of the invention the arrangement In the illustrated embodiment of the' of the trip or controller at the side of the shuttle-body cooperates with the rounded shape of the follower in permitting the spindle, with the follower thereon, to be raised and lowered freely in the usual manner without hindrance through the engagement of the follower with the trip of controller. The movement of the spindle into its elevated position carries the follower away from the trip or controller, so that the latter, under the action of its spring 11, assumes its normal or operative position. When, however, the spindle is depressed into the cavity of the shuttle, the rounded periphery of the follower on coming in contact with the tail of the trip or controller operates to press the said tail to one side, thereby moving the trip or controller into its inoperative position. (Represented in Fig. 3.)

What I claim i s-- 1. In a loom-shuttle, in combination, the receiver for the working weft-supply, a follower mounted to move in the direction of the length of the weft-receiver and controlled as to such movement by the mass of yarn constituting the said weft-supply, and a movable trip or controller held in abnormal position by the said follower and released to assume its normal position by the movement of the follower lengthwise of the weft-receiver, which is permitted by depletion of the said working weft supply to the predetermined extent.'

2. In a loom-sh uttle, in combination,a'weftreceiver to hold a cop of weft or filling, a spring-actuated follower to coact with the base of the said cop, movable lengthwise of the said weft-receiver,and adapted to be held in an abnormal position by the said base, and a trip or controller movably connected with the shuttle-body, having an engaging portion adapted to occupy a position in which to cooperate with outside instrumentalities, the said follower engaging with the said trip or controller to hold the latter in abnormal position until permitted by the unwinding of the cop to become disengaged from the trip or controller. 7

3. In a loom-shuttle, in combination, the spindle, the follower applied thereto, the spring acting in connection with the said follower to press the same against a cop of weft or filling on the said spindle, and the springactuated trip or controller engaged by the said follower and thereby held in an abnormal position, the said trip or controller moving into its normal position when by the unwinding of the cop the follower is permitted to release the same.

In testimony whereof I affix my signature in presence of two witnesses.
